<p>A composite stent graft has a balloon expandable stent portion ( 3 ), a tubular graft material portion ( 1 ) inside or outside of the balloon expandable stent portion and self expanding stents ( 5 ) associated with the tubular graft material portion. Part ( 7 ) of the balloon expandable stent portion can extend beyond the proximal end ( 9 ) of the tubular graft material portion. The tubular graft material can be polytetrafluoroethylene, Dacron, Thoralon(TM), polyamide, small intestine submucosa, collagenous extracellular matrix material, or any other suitable biocompatible material. A method of deploying which includes flaring a part ( 7 ) of the balloon expandable stent portion is also discussed.</p> |
